In this post lets talk about, making lives easier while testing django models and forms. This is the fourth article in our Test Driven Development Series. Until now, we have already talked about intro to TDD, basic testing django views and models and functional testing with selenium.

Testing Django Models
=====================

By default when django runs against sqlite backend it creates a new in memory database for a test, based on the fixtures which you have kept. Application fixtures are a great way to test, but these are limited to the cases where you have a constant data model. But the projects we deal with are much more complicated than just having simple models, and manually managed fixtures are an inflexible solution for providing the test case data. Test fixtures are hard to maintain, when trying to reproduce complex referential associations. Doing it manually or monkey patching gets us into more trouble as we fail, more often than not in mainta
